城市地下工程穿越既有建筑物加固技术及工程应用

Technology and It’s Applying in Reinforcement for Urban Underground Structure Intersecting Another Existed Structure

结合城市地下工程规划建设中的环境问题、工程结构与环境技术问题,根据现有城市地下工程穿越既有建筑物的各类工程实例情况,总结了工程加固中多种设计的新思路及施工新技术方法。通过一个工程实例较详细地介绍了"桩板支护法"在某城市机动车隧道近距离上跨已建地铁双线盾构隧道工程中的应用。同时对今后研究的重点工作提出了几点建议。

Based on the environment and structure problem in urban underground projects＇ planning and constructing some new design method and construction technique in structure＇s reinforcement were summarized in this paper. The applying of Piles and Plate Bracing Method in protecting a shield tunnel which under another existed tunnel during the tunnel＇s construction was introduced in this paper. The key to the study in the future was suggested and some advices were approved. This paper made a good example for the future similar engin eering.
